UN/LOCODE
From Wikipedia, the free encyclopedia
|
UN/LOCODE, the United Nations Code for Trade and Transport Locations, is a geographic coding scheme developed and maintained by United Nations Economic Commission for Europe (UNECE), a unit of the United Nations. UN/LOCODE assigns codes to locations used in trade and transport with functions such as seaports, rail and road terminals, airports, post offices and border crossing points. The first issue in 1981 contained codes for 8,000 locations. Twenty-five years later, Issue 2006-2 contained 54,705 locations in 243 countries.[1]
UN/LOCODEs typically have five characters. The first two are letters, and come from the ISO 3166-1 alpha-2 country codes. Normally three letters will follow, but if there are not enough combinations, numbers from 2 to 9 can also be used. For airports, the three letters following the country code are not always identical to the IATA airport code. According to the secretariat note for Issue 2006-2, there are 720 locations showing a different IATA code.[2]
Beside the abbreviation, UN/LOCODE also defines a spelling for each location that can be written without special characters. This is achieved by stripping off the diacritics from the (romanized) local name.[2]

- Explanations
- US NYC for New York City in the United States. Subdivision is the U.S. state of New York (see ISO 3166-2:US). Function: port, rail, road, airport, postal. IATA code is NYC. Coordinates: .
- DE BER for Berlin (city) in Germany. Subdivision is the German state of Berlin (see ISO 3166-2:DE). Function: port, rail, road, airport, postal. IATA code is BER. Coordinates: .
- DE TXL for Berlin-Tegel Airport in Germany. Function: airport. IATA code is TXL.
- FR PAR for Paris (city) in France. Subdivision is the French department of Paris (see ISO 3166-2:FR). Function: port, rail, road, postal.
- GB PAR for Par in United Kingdom. Subdivision is the English county of Cornwall (see ISO 3166-2:GB). Function: port.
- SE GOT for Göteborg (Goteborg without diacritics) in Sweden. Subdivision is the Swedish county of Västra Götaland (see ISO 3166-2:SE). Function: port, airport, postal. The IATA code of XWL indicated in the table is that of a train station in the city centre of Göteborg (though not the Central Station), while the IATA code for the main airport (Göteborg-Landvetter Airport) is actually GOT. It also has a separate reference entry showing an alternate spelling of Gothenburg.
- Ch (Changes)
- A change from the previous issue is indicated by one of the following characters in the first column:
- + Additions to the issue
- # Change in location name (usually spelling)
- | Change other than location name
- X Entries marked for deletion in the next issue
- = Reference entry
- ! US locations with duplicated IATA code, under review
- SubDiv (Subdivision)
- The ISO 1 to 3 character alphabetic and/or numeric code for the administrative division (state, province, department, etc.) of the country, as included in ISO 3166-2/1998. Only the latter part of the complete ISO 3166-2 code element (after the hyphen) is shown.
- Function
- Each defined function gets a number; the most important are: 1 = port, 2 = rail terminal, 3 = road terminal, 4 = airport and 5 = postal exchange office.
- Status
- Indicates the status of the entry by a 2-character code. The following codes are used at present:
- AA: Approved by competent national government agency
- AC: Approved by Customs Authority
- AF: Approved by national facilitation body
- AI: Code adopted by international organisation (IATA or ECLAC)
- AS: Approved by national standardisation body
- RL: Recognised location - Existence and representation of location name confirmed by check against nominated gazetteer or other reference work
- RN: Request from credible national sources for locations in their own country
- RQ: Request under consideration
- RR: Request rejected
- QQ: Original entry not verified since date indicated
- XX: Entry that will be removed from the next issue of UN/LOCODE
- Date
- The date the location was added or updated: 0207 is July 2002, 9501 is January 1995, etc.
- IATA
- The IATA code for the location if different from the second part of the UN/LOCODE.
[edit] Errors
Occasionally locations are listed twice. In issue 2006-1, ARSMC San Miguel de Tucuman (functions 2,3) was added while ARTUC Tucuman (function 1) already was in the list. The coordinates are with very little deviation the same. Also in 2006-1, ARSSJ San Salvador de Jujuy was added (function 4) while ARJUJ Jujuy (functions 1,2,3,5) already existed.
